No sound in Android x86

I installed an Android-x86 image (4.0-RC1-eeepc) in VirtualBox on a Dell Latitude D820. This particular ISO is not for a laptop, but of all the available ISOs, it works best.

I dealt with some problems that I encountered (not having an ISO for my device), but I could not get the sound to work. The Android-x86 VirtualBox tutorial and other online resources prompted me to use the ALSA driver with SoundBlaster 16, but that didn't work.

This question helped me take a look at some of the ALSA teams to see what I can find, but I won't go anywhere.

With the ALSA driver and SoundBlaster controller, I get the following from alsa_ctl init

 Unknown hardware: "Dummy" "Dummy Mixer" Hardware is initialized using a guess method

It looked very wrong for me, so I switched to Intel HD Audio, as well as to another question.

With the ALSA driver and Intel HD Audio controller, I get the following from alsa_ctl init

 Unknown hardware: "HDA-Intel" "SigmaTel ID 7680" ... Hardware is initialized using a guess method

Although this looks a little more promising, I still have no sound.

Since Android is basically Linux, I thought I could translate the Linux solution. Several web pages have content similar to this one saying to modify /etc/modprobe.d/alsa-base.conf and add options snd-hda-intel model=CORRECT_MODEL , and this seems to help many Linux users. However, this is not like Android. At least not for me, since I don't have alsa-base.conf

I know so little about audio and ALSA. Are there any jumps from what I have above? Even a push in the general direction would be great.

Some questions I have: What does it mean when I get Unknown hardware: "Dummy" ? No audio device?

Finally, I confirmed that my sound works outside the virtual box. My first question is that since my laptop can run Linux with sound, I should be able to enable Linux drivers in Android. Does this make sense? Unfortunately, I also do not know how to do this.

thanks

You had no problems with audio in vbox. In your init.sh, add this line to the end of the alsa_amixer file:

alsa_amixer set PCM 100 unmute

After I realized that my sound worked fine.

I had the same problems.

I used VMWare for WhatsApp. And had various versions of Android without sound ... Configuring VMWare with a modem HDAudio configuration configuration.

 alsa_ctl init

No devices showed up.

I installed this application from Google Play " AlsaMixer (ROOT) " And these versions got the sound instantly:

  • Android-x86-4.3-20130725.iso
  • Android-x86-4.4-RC1.iso

I had the same problem.

I continued to look for init.sh , and then realized that I needed to install the darn thing on the disk before it was worth messing with it (it is parsed again on reboot, and the live disk is not saved).

So, I hooked the last x86 ports and flipped them until I found 4.2x without any problems. Unfortunately, I lost track of that, and the good one is just vm.iso ?!

In short, the sound works fine with this assembly, I didn’t even need to configure anything.

System:

  • Motherboard Tab:
    • 4 GB RAM (half RAM)
    • [x] Hard disk (boot device only)
    • all others by default
  • Processor Tab:
    • 2 cores
    • all others by default
  • Audio:
    • Windows DirectSound
    • ICH AC97
    • all others by default

All you need to do in vbox is simply change it in the audio tab from Intel HD audio to ICH AC97. It actually works.

just unplug the USB audio rotation it will be 100% sure
